and there being a shoulder 57 at one end et the body. Movement of the slide or valve controlling device 53 in one direction is limited by an adjustable stop 58 such as a screw, threaded into the cap 46 and adapted The oil cap.

lligure 8 is a detail view wherein appears an oil cup 'denoted generally by the numeral 61. 'lbis cup 61 may be constructedin various ways, and some of the elements thereof may be omitted, if desired. As shown, the oil cup 61 comprises a bod 62 having a base -63 wherein a seatv 64 is as ioned, the base carrying a nipple, 65. A valve plug 66 is threadedY into the base 63 and controls the dow through the nipple or outlet65, a seat 67 being ormed inthe base .63' for the reception of the inner end oit 'the valve plu A cap 68 is threaded on the bogy 62 o the oil cup.

y ithin the body 62 of the oil cup 61, an. inverted cup-shaped plunger 69 is .slidably mounted. lin the bottom of the plunger 69 there are outlets 70. The numeral 71 designates a'hollow valve which is so shaped at Aits lower end as to conform to the seat 64,

the valve 71 comprising a neck 72 defining a shoulder 73, the neck being threaded into the bottom of the plunger 69 and the shoulder 73 engaging the bottom of the plunger. A tubular guide'74 is threaded on the inner end ot the neck 72 and, cooperating with the er end with azjreduced, openin 75. A 76 is disposed'within the gui e 74 and constitutes -a movable closure for-the openlng 75, the valve being held in closed position with respect to the opening' 75 bya Acompression spring 77 disposed within the ad 78 located 'dev74. A retarder or 1n the plunger 69 and' r s on thebottom thereof, the retarder Vbeing constructed et such material that oil'vvill pass through Vit slowly, lwhen the'oil-is under pressure. A cover late 7 9 rests on the retarder 7 8 and is lll@ bottom of the plunger 69, holds the valve' 71 in place.- 'lhe guide 74 isequipped in its lll@ rsa

locate about the de 74 the cover plate being held in place by a sp un; retainer 81 engagedV with the side wall ot the plunger 69. There `are openings 86 inthe plate 79.

vzo

14'; compression spring 82 is disposed in the body 62 of the oill cup 61 and exerts an up'- Ward pressure on the plunger 69.

The oil -cup is covered specifically in my zo-pending application Serial No. 625,904, led on the 17th day of March, 1923.

The pump.

.A pump 83 of any desired vsort-is supplied, the pump, if desired, including a casing 84 having an inlet 85 and an outlet 86, the casing being provided -with a-,fprojecting bearing 87 of any desired length. Upon the cas-V ing 84, a lid 88 is secured as indicated at 89. A stub shattV 90 is mounted in the bottom portion of the casing 84 and upon the stub shaft, a gear wheel 91 ais mounted, the gear wheel meshin into.a' gear wheel 92 secured at 93 to a s aft 94 journaled in the bearing 87, the shaft being, power-driven.

If the oiling system forming the subjectmatter of this application is applied to an automobile, the shaft 94 will be .driven in *any* appropriate way -from the propelling @0f/medians, piping and miscellaneous parte.

Anniversal joint 99 connects the slide 98 with a rod 100 which is pivoted vat 101 to thejlever 28./ as shown in Figure 2. One end of a sleeve 102 (which may be flexible) is connected at 103 to the bearing 104,- the other en d of the sleeve being gripped between thejaws 41 ofthe bracket 40.shown in Figure 3. Throu h the sleeve 102 passes an operating mem er 106, which'may be a wire, one end'of the operating member be-'- ving 4attached to the slide 105.

shows `that'the other end of the operating member 106 is received in the valve control. Vling slide 53 and is heldtherein bythe screw 60. Reverting to Figure 1, a by-pass con,

Figure 3 duit 107 extends between the outlet 36 ofthe receptacle 34 and the inlet 30 of the tank 1. A delivery conduit 108 is connected at one end tothe outlet 7 vof the valve casing 4..

The delivery conduit 108 has branches 109 which are assembled with thel caps 68 of the o ilcups 61. A. pressure conduit 110 eX- tends. between the outlet 33 of the ,body of the valve mechanism 31 andthe gauge 96.

Sundry observations may properly be made at this point concerning the stren h. yof certain springsin-the device. In or er1 `to'shorten the description, let it' besupposed that'the spring 52 of Figure 3 will yield -under a pressure of ten pounds; that the spring 82 of Figure 8 will yield under a pressure of ten pounds; and that the spring 77 of Figure 8 will yield under a pressureof thirty pounds; these figures being purely arbitrary, saving in so far as they may indicate a difference in the strength of the springs, relatively but not indegree. Let lit be supposed, further, by way of illustration, that the propelling force of the pump 83 is 'about sixty pounds. The pump 83 and the base 32 of the valve mechanism 31 are interposed in the delivery conduit 1,08. The

delivery conduit 108 may be of any length and shape, the particular form given to this element in Figure 1 beingselected merely lwith a view to economizing space.

Operation. p

In practical operation the valve 19 at the bottom of the tank 1 (Figure 2) is moved to open position by a train of elements com-` prising'the slide 98, the connection 100 and the lever 28. The lost motion aorded by the member 24 prevents the valve 19 from being opened iftlie slide 98 is touched or struck accidentally.v When the valve 19 is opened, the oil asses from the tank 1 through the open1ng-9-10 the screen 11,

the chamber 5, the chamber 6, thel outlet 7 and the conduit 108, into the pump 83. The 'pump' 83 passes the oil onward through the conduit 108 into the base 32 of the valve mechanism 31 (Figure 43), pressure being transmitted to the gage 96 through the conduit 110. The oil Hows under pressure through the conduit`108 to the cups-61 by way of the branches 109. The pressure of' oil in .the cup 61 forces the plunger 69 down-5fv wardly until the valve-Q71 closes upon thed seat .64, 4the spring 82 v'being compressed. The valve 76 does not open at this time because the, spring 77 is stronger than the spring 82. The pressure builds up in the conduit 108 andv in the cup 61 until -the gauge'f96 indicates theknown pressure at.

which the s ring 82fof vthe cup 61',and they A spring 52 o the valve mechanism 61' yield. Then, the operator manipulates the slide 98 tp cause the lever 28 of the tank 1 to permit the valve 19 to close under the action of the spring 23. If the operator 4does not closethe valve `19 promptly, the spring`52 of the valve mechanism. 31 (Figure 3) is compressed, and the oil which is fed through the conduit 108 b vthe pump 83 ,after the.

cup 61.has1bee n lled, returns tof'the tank 1 throulgh the by-pass 107. When the valve 19 at t 'e bottom'of the tank 1 closes,the

lao

' valve `51 shown in Figure 3closes responsive to the action of the spring 52, because no mor-e oil issupplied to the pump 8 3 to -be forced through the'conduit108.A When the pressure of oil in the cup 611s .reduced vby the operation last above described, the sprin 82 '(liligure 8) returns the cup-shape plunger 69 to theposition shown in Figure 8, the plunger being full of oil, and the i valve 7l being carried to open position with openings 70 of the plunger, the oil passing through the nipple 65 to the part Which is to be lubricated. rllhe plug valve 66, if used,

aifords afine adjustment of the oil supply.

Suppose that `the operator suspects that, due to an obstruction, some part which is to be lubricated by one of the cups 61 is not receiving a proper amount of oil. Then, both the slide 98 and the slide 105 areoperated, the slide 98 securing an opening of the valve 19 (Figure 2), and the slide 105 acting through the member 106 to move the.

valve controlling device 53 until the inclined edge V56 thereof lies moreor less in the .path of the valve stem 50, the position of the vvalve-controlling device being regulated by means of the, screw 58 which engages the shoulder 57. @il ows into the cup 61, `the plunger 69 moves downwardly, ,the valve 71 (Figure 8*) closes on the seat 64, 'and the plunger 69 tills with oil as hereinhefore described. 'llhe pressure is retained 'in the oil cup l61, under such circumstances, becausev theyalvel' 1 is closedupon the-seat 64.v rlihe valve 51(l1`igu`re 3) opens under the in-V creasing pressure of oil, but does not open fully, because the. edge 56 of the valve-conv trolling member 53 is disposed in the path inglre ofthe stem ofthe valve 51. Some of the oil passes b the valve 51 and enters the tank 1 through Vthe b'y-pass 107'. The pressure is increased in the oil cup 61, but is not increased -to full pump pressure. because the valve 51V vis opened slightly. Throughthe -nstrumentality of the stop screw 58, the

position of'tlievalve controlling member 53- may be regulated,the movement of the valve stem 50-being adjusted, the valve 51 being;

opened more or less, the amountof oil es# caping through theby-passl'? being varied,

and the ressure of oiliin the oil cup 6110eted 'accordingly'. The pressureP in the oil cup 61 builds up until -it vishigh enoughjto compress .the spring 77, Wherem 'upon the valve 76 'movessuddenly to open position with"respect to the aperture 75; The oil shoots, then, with great force, Vand "almost explosively, from the cup-shaped plunger 69 and the body 62 ot the cup '61, VVthtoughthe ripening 5, through the guide through the hollovvyalve YY1-and vthrough maaar? 105 to restore the valve-controlling device 53 to its normal position.

Should it be found that Qil from the chamber 6 leaks out through the space'QO, an inter-nal annular groove may be formed vin the tubular guide 16, and an oil hole, for reu turningoil, may be drilled from the chainber into the aforesaid groove.
